DeepBern-Nets: Taming the Complexity of Certifying Neural Networks using Bernstein Polynomial Activations and Precise Bound Propagation

1 code implementation22 May 2023 Haitham Khedr, Yasser Shoukry

In this paper, we ask the following question; can we replace the ReLU activation function with one that opens the door to incomplete certification algorithms that are easy to compute but can produce tight bounds on the NN's outputs?

BERN-NN: Tight Bound Propagation For Neural Networks Using Bernstein Polynomial Interval Arithmetic

no code implementations22 Nov 2022 Wael Fatnassi, Haitham Khedr, Valen Yamamoto, Yasser Shoukry

Bernstein polynomials enjoy several interesting properties that allow BERN-NN to obtain tighter bounds compared to those relying on linear and convex approximations.

CertiFair: A Framework for Certified Global Fairness of Neural Networks

no code implementations20 May 2022 Haitham Khedr, Yasser Shoukry

We propose a fairness loss that can be used during training to enforce fair outcomes for similar individuals.

Fast BATLLNN: Fast Box Analysis of Two-Level Lattice Neural Networks

no code implementations17 Nov 2021 James Ferlez, Haitham Khedr, Yasser Shoukry

In this paper, we present the tool Fast Box Analysis of Two-Level Lattice Neural Networks (Fast BATLLNN) as a fast verifier of box-like output constraints for Two-Level Lattice (TLL) Neural Networks (NNs).

PEREGRiNN: Penalized-Relaxation Greedy Neural Network Verifier

1 code implementation18 Jun 2020 Haitham Khedr, James Ferlez, Yasser Shoukry

However, unique in our approach is the way we use a convex solver not only as a linear feasibility checker, but also as a means of penalizing the amount of relaxation allowed in solutions.

Formal Verification of Neural Network Controlled Autonomous Systems

no code implementations31 Oct 2018 Xiaowu Sun, Haitham Khedr, Yasser Shoukry

In this paper, we consider the problem of formally verifying the safety of an autonomous robot equipped with a Neural Network (NN) controller that processes LiDAR images to produce control actions.
